IMPROVED WATER-PROOF VARNISH FOR PAPER, CLOTH, 81.0.

periticalion forming part of Letters Patent No. 39,095, dated June 30,1863.

T0 aZZ whom it may concern.-

Be it known that I, JONATHAN H. GREENE, of Ohristiansburg, in the countyof WVapello and State of Iowa, have invented certain Improvements inCompositions for WVaterproofing and Clarifying Textile Fabrics; and I dohereby declare that the following is a full ,clear, and exactdescription thereof.

My said invention relates to that class of compositions used chiefly torender cloths and papers clear and transparent, as well as waterproof,for various purposes for which such cloth and paper are used, among themost important of which may, perhaps, be mentioned that of tracingdrawings and various descriptions of designs. There are, however, otherpurposes to which this composition may be applied with advantage.

The said composition is composed of one part, by measure, oflinseed-oil, one part, by measure, of india-rubber cement, and sixparts, by measure, of benzine. This, for most purposes, constitutesprobably the best mixture; but for a preparation of tracing-cloth andtracing-paper of close texture it may be advisable to use an additionalproportion of benzine to avoid producing a gloss on the outside, andalso to avoid filling the pores of the paper too full to retain the inkand colors which may be applied. This mixture may be applied with abrush, or by other proper machinery or device, to the surface of thecloth upon which it is intended to operate, which should then besubjected to heat not exceeding 250 Farenheit, and for most purposes 200will answer very satisfactorily; and this heating should be continuedtill the compositi on has sufficiently penetrated the goods, and alsobecome sufficiently dry that when taken out and cooled it shall not betacky or sticky.

In addition to the preparation of tracingcloth and tracing-paper by thismeans, I also prepare an article intended to take the place pose toprepare withit bank-notes by saturating them with this composition,which effectually prevents their being photographed when anycolors areused in printing either side, and also gives durability to the bill,ease of manipulation in counting, and transparency,

which enables a person to see at a glance the effect of the engravingupon both sides. There are various other purposes to which thiscomposition may be applied, but which are obvious applications, whichwould be too tedious in number to enumerate.

The india-rubber cement spoken of is the article generally andtechnically known in trade by that name, and is a saturated solution ofindia-rubber in naphtha, camphene, or some other solvent. Thelinseed-oil should be boiled before being mixed with the otheringredients, though, if this is not done, it can be dried by anapplication of sufficiently strong heat. I suppose some other essentialoil or solvent might be used instead of benzine as a member of thiscomposition without entirely destroying the effect produced, which isdue, in a great measure, to the combination of in dia-rubber andlinseed'oil; but I prefer the use of benzine to any other solx'ent withwhich I am acquainted.

I claim The combination of linseed-oil,india-rubber, and benzinc, orsome equivalent solvent, substantially as and for the purpose set forth.
